Abstract
Various embodiments of the present disclosure include systems and methods for analyzing patents and prior art in a patent management system. In an example embodiment, a computer-implemented method of determining a potential point of novelty for an identified patent comprises retrieving at least one independent claim of the patent in the claim form as issued; retrieving at least one independent claim of the patent in the claim form as published; and automatically comparing the issued claim to the published claim by identifying unique keywords present in the issued claim but not present in the published claim and flagging the unique keywords to a user.
Claims9
A computer-implemented method utilizing at least one computer system for determining a potential point of novelty of a patent, the method comprising:
- electronically retrieving at least one independent claim of the patent as issued;
- electronically retrieving at least one independent claim of the corresponding patent application as published;
- automatically comparing the at least one issued claim to the at least one published claim to identify at least one unique keyword present in the at least one issued claim but not present in the at least one published claim;
- cross-referencing the at least one unique keyword to a passage in the specification of the issued patent;
- flagging the at least one unique keyword to a user;
- identifying at least one prior art document and at least one other prior art document;
- calculating an overlap score for the at least one prior art document based on at least one occurrence of the at least one unique keyword in the at least one prior art document;
- calculating an overlap score for at least one other prior art document based on at least one occurrence of the at least one unique keyword in the at least one other prior art document;
- calculating a ranking for the at least one prior art document by comparing the overlap score of the at least one prior art document to the overlap score of at least one other prior art document;
- displaying, in a user interface, a graphical representation of the overlap score of the at least one prior art document and a graphical representation of the overlap score of the at least one other prior art document based on the ranking;
- identifying a priority date of the at least one prior art document and a priority date of the at least one other prior art document;
- identifying an owner of the at least one prior art document and an owner of the at least one other prior art document;
- and
- displaying on a time line, in the user interface, the owner and the priority date of the at least one prior art document and the owner and the priority date of the at least one other prior art document.

A non-transitory computer-readable medium including instructions stored thereon, which when executed by at least one processor, configure the at least on processor to:
- retrieve at least one independent claim of the patent as issued;
- retrieve at least one independent claim of the corresponding patent application as published;
- automatically compare the at least one issued claim to the at least one published claim to identify at least one unique keyword present in the at least one issued claim but not present in the at least one published claim;
- cross-reference the at least one unique keyword to a passage in the specification of the issued patent;
- flag the at least one unique keyword to a user;
- identify at least one prior art document and at least one other prior art document;
- calculate an overlap score for the at least one prior art document based on at least one occurrence of the at least one unique keyword in the at least one prior art document;
- calculate an overlap score for at least one other prior art document based on at least one occurrence of the at least one unique keyword in the at least one other prior art document;
- calculate a ranking for the at least one prior art document by comparing the overlap score of the at least one prior art document to the overlap score of at least one other prior art document;
- display, in a user interface, a graphical representation of the overlap score of the at least one prior art document and a graphical representation of the overlap score of the at least one other prior art document based on the ranking;
- identify a priority date of the at least one prior art document and a priority date of the at least one other prior art document;
- identify an owner of the at least one prior art document and an owner of the at least one other prior art document;
- and
- display on a time line, in the user interface, the owner and the priority date of the at least one prior art document and the owner and the priority date of the at least one other prior art document.

- a network;
- a patent matter database, accessible on the network, and including data about the patent;

- a memory,
- software operable on the processor to:
- retrieve at least one independent claim of the patent as issued;
- retrieve at least one independent claim of the corresponding patent application as published;
- automatically compare the at least one issued claim of the patent to the at least one published claim of the patent to identify at least one unique keyword present in the at least one issued claim but not present in the at least one published claim;
- cross-reference the at least one unique keyword to a passage in the specification of the issued patent;
- flag the at least one unique keyword to a user;
- identify at least one prior art document and at least one other prior art document;
- calculate an overlap score for the at least one prior art document based on at least one occurrence of the at least one unique keyword in the at least one prior art document;
- calculate an overlap score for the at least one other prior art document based on at least one occurrence of the at least one unique keyword in the at least one other prior art document;
- calculate a ranking for the at least one prior art document by comparing the overlap score of the at least one prior art document to the overlap score of at least one other prior art document;
- display, in a user interface, a graphical representation of the overlap score of the at least one prior art document and a graphical representation of the overlap score of the at least one other prior art document based on the ranking;
- identify a priority date of the at least one prior art document and a priority date of the at least one other prior art document;
- identify an owner of the at least one prior art document and an owner of the at least one other prior art document;
- and
- display on a time line, in the user interface, the owner and the priority date of the at least one prior art document and the owner and the priority date of the at least one other prior art document.
